REGISTER.

Specification of Letters Patent.

Patented Aug. 20, 1918.

App1ication filed August 21, 1915. Serial No. 4652?.

To all whom it may concern Be it known that I, CYRUs S. Hoop, a citizen of the United States, and resident of Corning, in the county of Steuben and State of New York, have invented certain new and useful Improvements in Registers, of which the following is a specification This invention relates to certain improvements in registers and more particularly to that type which is adapted for use at the intersection of a floor and a wall. A register of this type and in which register faces extend in vertical and horizontal planes is shown in my prior Patent No. 4155,563, issued December 22nd, 1891.

One of the main objects of my present in vention is to so construct the dampers that the amount of air passing through the horizontal and vertical register faces may be simultaneously controlled and the dampers held in any predetermined adjusted position. A further object of my invention is to secure a very simple, inexpensive and easily operated means for connecting the register to the register boX. Various other objects, advantages and novel features of my improved construction will be pointed out more particularly hereinafter.

Reference is to be had in the accompanying drawing in which similar reference characters indicate corresponding parts in the several. views and in which I have illustrated one embodiment of my invention. I desire it specifically understood that the form shown in these drawings is only one of various forms which my invention may assume and that various changes may be made with in the spirit of my invention and without departing from the scope of the appended claims.

In these drawings Figure 1 is a face view of the wall portion, the floor portion being shown. in section,

Fig. 2 is a vertical transverse section on the line 22 of Fig. 1,

Fig. 3 is a section similar to a portion of Fig. 2, but on an enlarged scale, and 7 Figs. 4- and 5 are perspective views of details.

In the specific form illustrated, the register face includes two reticulated plates 10 and 11 one adapted to extend in a substantially vertical plane and the other in a horizontal plane. These are shown as being integral and formed from a single piece of sbeetmetail but it is of course evident that they might be made of separate pieces which might be interlocked or fastened together in any suitable manner along the line of intersection. The floor plate 11 is de signed torest upon the upper surface of the floor A and approximately flush with the latter while the wall plate 10 is preferably constructed so as to stand out from the wall B a distance equal to the thickness of the base-board C so that its outer surface may liesubstantially flush with the outer surface of the latter. For this purpose, the wall plate 10 is provided with side flanges 12 and a top flange 13, the width of each of which may be substantially equal to the thickness of the base-board C. They might be wider or narrower or might be omitted. The flanges are preferably integral with the wall register face 10 and may be overlapped and riveted or welded together at the upper corners so as to hold the structure rigid, the

lower ends of the side flanges 10 may terminate substantially flush with the under surface of the edge portions of the floor register face 11 and rest upon the floor.

Two separate dampers 1e and 15 are provided, the former in connection with the floor register face 10 and the latter in con- 'nection with the wall register face 11. These dampers may be of substantial flat sheet metal plates each pivotally mounted adjacent one edge of its corresponding register face and when, ili'ClOSQd position, lie closely adjacent to the inner surface of the latter. Its edges may be bent slightly toward the face so as to make a substantially tight fit when closed. i

The mechanism for supporting and operating the vertical damper 15 embodies one important feature of my invention. The damper is supported at its upper edge, the hinge or pivotal support being only along the center portion of the upper edge and not extending to the side edges of the damper. As shown, the register face is provided with an inwardly or rearwardly directed flange 16 preferably formed of sheet metaland riveted or welded to the rear surface of the face. Secured to the lower side of the horizontal portion. of this flange is a rod 17, the end portions of which are welded or secured in placein any other suitable manner, while the intermediate portion is bent downwardly so as to be spaced a short distance fromsaid flange. A. plate 18 is riveted, Welded or otherwise secured to the rear surface of the damper adjacent to the upper edge and from the lower edge of this plate are two upwardly extending arms 19, the upper ends of which are curved so as to partly embrace or encircle the rod 17. Screw bolts 20 extend through the spring arms 19, the plate 18 and the upper edge of the damper so that upon tightening of the bolts, the rod is more or less tightly clamped between the curved upper ends of the spring arms and the upper end of the body of the plate 18, and the damper is permitted to swing about the rod 17 as an axis. As the rod cannot rotate and the friction between it and the spring arms varies with the tightening of the bolts, it is evident that this friction may be such that the damper will remain in any angular adjustment at which it is placed, and will thus stay in open, closed or any intermediate position. To permit this friction to be increased or decreased without removing the register, the screw bolts preferably have slotted head exposed to view at the front side of the damper and the nuts are held against rotation by any suitable stops, such for instance as the curved upper ends of the spring arms. By the use of a screw driver, the screw bolts may be rotated to loosen or tighten the nuts and vary the clamping action on the non-rotatable supporting rod 17.

To operate the damper any suitable projectin-g member may extend through the register face. I preferably provide the plate 18 with an arm 21 extending through a slot in the damper and an aperture in the register face so that by grasping the upper end of this arm, or handle 21, the damper may be opened or closed. As the damper is supported only along the center portion of the upper edge, the upper corners are free and therefore may be bent forwardly so as to resiliently engage with the register face when the damper is closed and a tight fit insured.

The floor damper 14: is pivoted in any suitable manner at its rear edge which is disposed adjacent the line of intersectionof horizontal and vertical register faces. As shown, the rear edge of the floor damper encircles a pivot pin or pivot pins 21, the ends of which enter depending flanges 22 secured to the under surface of the floor register face 11. For operating the floor dam-per 1% simultaneously with the operation of the wall damper 1 5 the latter is provided with an arm 23 extending forwardly from its lower edge and so formed and so mounted that when the damper 15 is in closed position the end of this arm 23 will engage with and support the damper 14 at a point some distance in front of the pivotal support of the latter so as to hold it in closed position. As the wall damper .15 is opened, its

vrear edge swings rearwardly and the front end of the arm 23 swings downwardly and rearwardly so as to permit a corresponding opening of the floor register. IVhen the wall register is in its full open position the arm 28. may be entirely free from the floor damper and both will be open.

I preferably limit the opening movement of the floor damper so that it cannot swing through much more than 45. This insures a proper distribution of the air to the two register faces and prevents the floor damper from reaching such a position as might interfere with the free delivery of air to the wall register face. Any suitable stop may be provided for limiting this movement of the floor damper butpreferably I strike out portions of the side flanges 22 so as to form lugs 24. These are so positioned that they are in the path of the side edges of the floor damper and limit the swinging movement of the latter. The arm 23 may be secured to the Wall damper in any suitable manner. Preferably it is in the form of a strap of sheet metal welded or riveted to the wall damper and bent forward substantially at right angles to the plane of the latter although it may be otherwise formed if desired. The forwardly extending portion may have such resiliency as will insure the proper tight closing of the floor damper. To reinforce the strap at the angle, the strap may be curved laterally at this point so as to form a bulge or bead.

The flanges 16 and 22 which are secured to the floor and wall register faces serve not only to support the dampers but also extend within the walls of the register box so that the register faces will form a substantially air tight fit with the box. This box 26 is so designed as to deliver air beneath the floor register face and in the rear of the wall register faces and has its edges secured to these faces. The edges of the front portion of the register box preferably extend up outside of the flanges 22 and are bent over so as to engage with the upper surface of the floor where they and the register face may be held down in any suitable manner as for instance by screws 27. For securing the vertical edges :of the register box to the vertical register face, I preferably provide strips 28, each in the form of a small angle strip. The register box is secured to one flange of each strip in any suitable man ner as for instance by having lugs 29 or extensions projecting through slots in the strip substantially as shown in Fig. 5, while the other flange of each strip engages with the rear surface of vertical register faces and is secured to the latter by small-bolts or screws 30. Thus to remove the register,

it is merely necessary to remove the screws 27 and 30 and this will entirely free the reg aster from the register box. When the screws are in place, the edges of the register box are firmly held to the register faces outside of the flanges 16 and 22 so that there is very little if any leakage of air from the register box, all of the air passing through the register faces when the dampers are open.

As I have previously indicated, I do not desire to be limited to the specific details illustrated in the accompanying drawings as hereinbefore described, nor do I desire to be limited to the use of certain of these features in a combined floor wall register. Many of the features such for instance as the means for supporting and operating the wall damper and the means for screwing the register box thereto might be embodied in a register in which there was merely a wall face but no floor face and likewise certain of the features might be employed in a damper having merely a floor face but no wall face.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A. register including a wall register face, a floor register face, a damper pivotally supported in the rear of the wall register face adjacent the upper edge of the latter and of substantially the same size as said first mentioned face, a damper pivotally supported adjacent the rear edge of the floor register face and of substantially the same size as said second mentioned face, and means for opening or closing said dampers simultaneously.

2.
